This is the 4 pin plug for the brutus
This is the left side of the PB110a booster box. The group of 4 wires are INPUT only from the transformer. To provide the needed current capacity Pins 1 and 2 are grouped together, 3 and 4 are also grouped together. The photo shows the pre wired 4 pin plug included with the 18VAC /10 amp Brutus power supply. Plug and play! However any supply can be used that does not exceed 22VAC / 32VDC. You also see a small 4 wire phone cable (RJ-H). This is the control bus cable that gets the DCC signal from the command station CS02. The power light should be a solid red. A fast flash means no data from the command station. A slow flash indicates a track short!
Below, This is the right side of the CS02 Command Station box. You see the control bus cable (RJ-H) going out to the booster. The cab bus jack (RJ12) is also located here. You can plug in an RB02 radio base station, a cab of any kind, or a cable that goes out to a cab panel (UTP). Power for the CS02 is provided by the 2 pin plug shown. Included in the PH10 an 18VDC /1A power supply prewired with a 2 pin plug.
Here is everything together:
The track output follows the same rule as the power input. Pins 1 and 2 are for rail A. Pins 3 and 4 are for rail B. Notice that I did not specify a polarity! This is PWM-AC not DC on the rails.
